Question
Two projectiles are launched simultaneously from the
same point with equal initial speeds but different angles θ and (90°– θ). Which of the following is true about their time of flights and ranges (neglecting air resistance)?Solution
When two projectiles are launched from the same point with equal initial speeds but at angles θ and (90° – θ), their behaviour can be understood using basic projectile motion equations. 1. Time of Flight (T) Time of flight is given by: Thus, time of flights are different , unless θ = 90 ° 2. Range (R) Range is given by:
So, both projectiles have the same range . Therefore, the correct answer is option (b).
